Very helpful and complete manual. Maybe only one negative is schematics have sometimes unreadable name of the parts. But it's not a big problem.

Excellent high quality schematics brought my old Heidelberg back to life. Fast download at a reasonable price. Thanks.

This document is just what I was looking for, it´s very useful, it contains adjustment procedures for the final stage of the power amp and also
has a complete wiring diagram and description of the main semiconductors used in the design.

Dear Sirs,
Thank you for the fast support, the manual does provide all necessary information to repair the radio. All schematics are in a good quality for reading.
The manual fits 100% to my requirements as a technican.
Kind regards Thomas

the big video recorder format s-vhs many features delicate in loading system of the cassette. Such machines are no longer manufactured, it would be too expensive.

COPY QUALITY ADJUSTMENT
PARALLELOGRAM IMAGE ADJUSTMENT
The 1st and 2nd scanners are mounted perpendicular to the scanner rod in the factory. If they are not mounted perpendicular, a parallelogram image may appear. Since they cannot be reinstalled in the field correctly, the mounting screws must not be removed. The 4th and 5th mirror units have an adjustment screw on the bracket that can change the angle to the lens. If this angle is not correct, a parallelogram image also appears. This position is adjusted in the factory, however, it can be changed in the field by the following procedure if necessary. There is no need to adjust this screw position under normal usage conditions. The parallelogram image caused by the incorrect 1st and 2nd scanner mounting angle cannot be fixed by this adjustment.
